When you piss in your lovers mouth and then proceed squeeze out a chocolate doughnut and hold it between your ass cheeks. Then take your ass, position it over your lovers mouth and proceed to dunk your doughnut in her piss filled mouth.
Last night I dunked a bakers dozen of doughnuts in my wife's mouth. It was extremely satisfying.
My wife was open to the new idea of "dunking the doughnut".
